Specification of Letters Patent.

TABULATING-STOP FOR TYPE-WRITERS.

Patented April 2o, 190e.

To all whom it may concern.'

Be it known that I, J FRANK ALLARD, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new -and useful Improvements in Tabulatinging the shifting and stopping the carriage of a typewriter' at any predetermined point for securing exact vertical ahneinent of figures or words, as 1s necessary in the writing of tables, bills, and other kinds of schedule work.

The invention has for its main object the provision of a single key which may be readily and quickly operated to effect a release or shift the carriage and stopit at any point or denomination in a column of figures, without using the space bar or regular carriage-releasing means, and without being under the necessity of observing anything else than the movement of the said single tabulating key.

To these ends the invention consists broadly of a depressible and laterally-movable tabulating key lever which operates to shift and adjust the rocking and laterallymovable tabulating stop-rod so as to bring the stops to any desired point and also to release the carriage so that it may be stopped by an adjusted stop on the rod or by other means, all as I will now proceed to describe in detail and subsequently point out with particularity in the appended claims.

Reference is to be had to the annexed drawings and to the^letters marked thereon forming a part of this specification, the saine letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings-Figure 1 is a perspective view of my invention and parts with which it is immediately connected and operates, portions being shown as broken away in order to more clearly show articular parts and features. Fig. 2 is a p an view of the saine, portions being shown in section. Fig. 3 is an end view of the same. Fig. 4 is a perspective view of the column stop forming part of the'mechanism and Fig. 5 is an end view of said stop with parts broken away.

In the drawings-a designates the machine frame.

l) is the stop-rod or bar provided with holes c formed longitudinally therein from' its ends into which journal pins d d extend from the frame, so that the said bar b may be both rocked and moved longitudinallyon said journals.

At one end (the right-hand end, as the invention is herein represented) the stop bar and ournal pin are surrounded by a sleeve e, and a helical springf connected at one end to the frame a and at the other to the stop-bar surrounds the said sleeve and bar and operates to return the latter device to normal position when rocked and shifted longitudinally by the tabulating lever, as will be presently explained. The sleeve is provided at its outer end with a flange through which it is secured to the frame by means of screws g.

Supported by the up er ends of brackets 7L h connected at their ower ends with the stop-rod is a bar t having a scale inscribed thereon corresponding to the cylinder scale (not shown) in front of the machine so that stops y' on the stop-bar b may be set thereon with certainty with respect to the cylinder scale, a pointer le extending u from the stop to and over the scale-bar t to indicate the position of the stop relatively to the cylinder scale. The stops are maintained in set position on the stop-bar b by teeth thereof engaging width the teeth formed on said bar.

Z designates a short bar secured to the frame a and provided in its upper side with teeth adapted to be engaged by a linger m, projecting forward from a bracket h, when the stop-bar and its equipments are rocked forward, as will be hereinafter explained.

a designates another finger connected with the stop-bar which extends forward over the free end of a lever o, which, when depressed as it will be by the finger n when the stop-bar is rocked forward, will operate the dogs so as to allow the carriage to shift or be shifted.

p is the tabulating key-lever which at its front end extends through the front plate of the machine and is provided with a key g, and at its rear end has a loose connection with a finger r projecting from the stop-bar.

lAt an intermediate point the lever p is vertically and horizontally pivoted upon a bracket s or other part of the frame so that the key end of the said lever can be depressed and moved horizontally, operating the rear end of the level' in the same manner, and through its connections with the stop-bar rocking it on its journal pins and moving it longitudinally.

t is a plate adapted to be secured to the front plate of the machine, and having a scale u inscribed thereon, which scale cordinates, so far as it goes, with the cylinder scale. The forward end of the tabulating key-lever p projects through the scale plate t, and is provided with a pointer o projecting in close proximity to the scale.

The tabulating key-lever p is shown as bent or crooked, but the form shown is given to it merely to kee it out-of the way of other parts of a mac iine to which is may be ap lied. lt would perform its functions as wel if it were made straight or of other shape than that shown.

Vith this description of the construction and arrangement of the invention and parts with which it is related, a brief description of the mode of operation will be given: The stops j on the stop-bar when brought within the path of travel of an abutment or projection w of the carriage will arrest the travel or shifting movement of the carriage. Hence, if columns of figures of a table are to be written, the stop will be set on the line where, say, the period dividing the cents from the dollars will occur; Under this arrangement the entire extent to which the sto s may be shifted or adjusted may be uti ized for Writing iigures designating dollars, and inserting commas dividing the hundreds from the thousands and the latter from the millions. lf the smallest amount is to be written (say, cents only,) the stopley will be simply depressed which will not shift or adjust the stop-bar, but release the carriage and allow it to run forward until it is arrested by the stop in normal position, which will be on the line of the periods, as before stated. lf the largest amount to be written is ten million, as indicated in the drawings, the operator by shifting the lrey g to the left will move the stop-b ar to adjust the stop so that it will arrest the carriage ten points in advance of the point upon which it would normally be arrested, or at exactly the point where the writing of ten million should begin. Supposing again the maximum amount in a table to be 10,000,000, as is inscribed on the scale a, and that in one line it is proposed to write 10,000the operator by shifting the lrey q and moving it and the outer end of the lever p to the left six degrees of the scale a, will shift the stop-bar l) and stop correspondingly, causing the shifting movement of the carriage to be arrested exactly on the line where the writing of ten thousand is to be begun. The finger m having engaged the teeth of the rack-bar Z will assist in supporting the stop-bar b against the slamming action of the carriage on being arrested in its'shifting movement by the stop.

It will be seen that with this invention, the stop j will be set to arrest the carriage in its shifting movement at that line in the column where the period dividing the cents from the dollars is to be written, by depressing the tabulating key g. By shifting this lrey to the left, the lever y) will be operated to adjust the stop y' on the stop bar l) to the right so as to stop the carriage at any desired point from the period to the ten million line. Of course, as indicated in Fig. l of the drawings, more than one step may be employed on the stop bar to arrest the shifting traverse of the carriage at different points when more than one table or other column of work. is to be written, just as has been done heretofore in tabulating devices.

From the foregoing description it will be seen that the stop bar constitutes a movable carrier upon which the adjustable stop or stops are mounted and that a movement of the stop bar or carrier in the line of the movement of the carriage will determine the point or points at which the carriage is to be stopped and that this movement of the stop or stops with the carrier in no way affects the adjustment of the stop or stops with respect to the carrier.

By the use of my invention much time and trouble is saved in shifting the carriage for the reason that the carriage is stopped with certainty at exactly the point at which the writing is to begin without jumping the carriage forward. from the extreme limit to the said point. Moreover, the operator is not obliged to make special observation of the position of the carriage with respect to the cylinder scale.

The special and important feature of my invention is the stop key lever which is cngaged with and shifts or adjusts the stop bar and stops for the purpose explained whatever may be the form or arrangement of the parts mentioned.

It will be apparent that the key lever y), when depressed by the operator will cause the stop-carrying bar to be turned so as to bring the finger m into engagement with the rack l; the finger and rack by their engagement are adapted to receive the impact which is transmitted to the bar l) when the abutment stop w collides with the column stop j upon the release of the carriage, and thus a longitudinal displacement of the bar b and of the carriage, after the two stops have come into engagement, is positively prevented., and the stop is held immovable in the position to which it has been adjusted by the lateral movement of the key y. The same function of holding the stop j nd the carriage, when it jumps into contact with .llO

said stop) against longitudinal movement, is also etiected by the engagement of the key lever p between two ot the teeth shown at the lower portion of the plate t. r.there is thus a double security against the longitudinal movement of the bar t under the impact ofthe carriage, and these two holding or retaining means are connected with the bar b at opposite sides et the point of impact (the stop j), so that the structure is exceedingly rigid. The key lever p, therefore, not only serves to adjust the stop but also, by cooperating with the teeth on the plate t, as described, assists f ing the bar l) and the stop in the adjusted position as long as the operator holds the key g down. At the same time, the lever y) in connection with the bar t, the 'linger n and the lever o forms means for actuating the release mechanism of the carriage. Further, the sides of the recess in the upper pori on oi" the plate z5 serve to mechanically limit the adjustment or thr iv of the lever p and consequently of the stop also. Finally, it will be understood that the stop is held on the bar l) by means of a toothed spring-pressed finger j, Which forms an independent y mounted spring-pressed device for locking the stop in position on the bar.

By reason of the pressure of the spring f the key g Will normally remain in the eX- treme right hand position in the recess in the plate t, which position is indicated the decimal point on the scale a, With which the plate t is provided. The key q is provided With a pointer o, and this pointer o in connection With the scale a may be.

termed a selecting device, because by its aid the operator is enabled to select the proper column in which to Write the irst igure of the desired number. The lower part of the recess in the plate t, as above stated, is provided With a series of teeth so placed that the spaces or notches between them come directly under the divisions of the scale a. In order to adjust the position of the column stop the key q is first moved horizontally to the left until the pointer o cooperating With the scale 'a indicates the column in Which the first iigure of the desired number is to be written. rlhis movement produces a corresponding movement of the stop bar t, and of the stop upon it. The key g is then depressed for the purpose of moving the column stop into the path of the stop w upon the carriage, which stop fw is termed the denomination stop. Upon depressing the key g, it Will enter the space between the teeth on the plate t corresponding to the division on the scale u indicated by the pointer o, and Will be thereby detained or prevented from moving side- Wise, and with 1t also the stop bar b and the column stop y', as long as the key q is depressed. At the same time, the linger 4or detent m will engage with one of the teeth of the rack Z and detain the stop 7' in a similar manner and thus cooperate with the key g, when in engagement with one of the notches of the plate t, in withstanding the impact of the moving denomination stop w. The carriage will thereby be arrested in the desired Working position, and the cariage spring will keep the denomination stop w in contact with the stop y' and in the Working position, until the key g is released. Upon depressing the key g the escapement will be released automatically from the carriage, and on releasing the key q, the escapement Will again engage and retain the carriage in the desired Working position. The tabulating mechanism will then disengago from the carriage and return automatically to its initial position.

Since the adjustable bar of my device is entirely free from and independent of the carriage, it is obvious that my attachment can be applied to any of the leading types of machines, Whether they have a hinged carriage or Whether, as in the case of the Smith Premier machine, the sliding carriage has no hinged movement.
